                This spec leaves User.current in an unclean state, creating a dependency to other specs.

                It sets User.current to a value other than User.anonymous but does not clean up after the
                spec is run. User.current saves this value in an instance variable of the User class.
                This class instance variable is not removed between tests.

                So please go ahead and set User.current to nil afterwards.
